Issue:

Your pipes long description is being altered to have odd numbers: 

PIPE, S/XS SMLS, ASTM A-10292 11/16 GR B

Causes:

Stretching pipe to a different length after the initial placement

Solution:

Locate the erroneous items in your model. One method is to use the Find tab on the Lineview Palette to locate odd long descriptions in the model.

Once found, type CONVERTFROMPRJDATA at the AutoCAD command line and select the erroneous pipe.

Notes:

Turning off Apply Pipe Healing Rule has helped in many cases.
